SYNTHETIC INTERMEDIATE OF 1-(2-DEOXY-2-FLUORO-4-THIO-ß-D-ARABINOFURANOSYL)CYTOSINE, SYNTHETIC INTERMEDIATE OF THIONUCLEOSIDE, AND METHOD FOR PRODUCING THE SAME
The reduction of organic halides with tributyltin hydride in the presence of a catalytic amount of triethylborane has been studied. (1) Alkyliodides and alkyl bromides reacted easily with tin hydride at −78°C to give the corresponding hydrocarbons, while alkyl chlorides were sluggish to react and recovered unchanged. (2) The reduction of alkenyl halides such as 1-deuterio-1-iodo-1-dodecene and 1-

By mediation of BF3.Et2O, dithio-substituted cinnamyllithium 2 reacted predominantly at the α-site with carbonylcompounds. No selectivity was found when the reaction was performed in the absence of BF3.Et2O.
